Cummins 3927286 Cylinder Head Assembly

This complete cylinder head assembly is manufactured to OEM specifications for the Cummins 6BTA5.9 5.9L inline six-cylinder diesel engine. The casting is produced from high-grade cast iron to withstand high combustion pressures and thermal cycling. The assembly includes intake and exhaust valves, valve springs, retainers, keepers, and stem seals, ready for installation. The 6BTA5.9 engine utilizes a 12-valve overhead valve (OHV) configuration with mechanical fuel injection. This cylinder head replaces Cummins OE part numbers 3927286, 3934761, 3934769, 3934795, and 3967455. It is designed for use in industrial, construction, and commercial vehicle applications powered by the 6BTA5.9 engine platform. Dimensional accuracy and metallurgical composition are controlled to ensure proper head gasket sealing, valve train geometry, and coolant flow distribution.
